Abstract
The utility model relates to a suction filter device for a chemistry experiment, which comprises a filter device and a gas suction device, wherein the filter device comprises a crucible and a liquid separating funnel, an opening of the crucible is sealed by an elastic rubber ring; the bottom of the liquid separating funnel is provided with a speed regulation switch; the filter device is connected with the gas suction device through a flexible pipe; the flexible pipe is provided with an anti-reverse suction device; the gas suction device comprises a water inlet pipe, a sealing container and a water outlet pipe; the lower end of the water inlet pipe is connected with the upper end of the water outlet pipe through an inner pipe; the inner pipe is arranged in a sealing container; and a receptor is arranged below the water outlet pipe. In the suction filter device for the chemistry experiment, the anti-reverse suction device is arranged on the flexible pipe between the filter device and the gas suction device so that inverse suction caused by faults of a vacuum pump in the suction filter process can be prevented, the speed regulation switch can control the speed of liquid flow, and the suction filter effect is good.
Description
Technical field
The utility model relates to the suction filtration device, relates in particular to chemical experiment suction filtration device.
Background technology
Often adopt the mode of filtering that sample is carried out Separation of Solid and Liquid in the chemical experiment, the filter that is adopted is to be made of separatory funnel and crucible, and it is simple in structure.The general recirculated water vavuum pump that uses vacuumizes, but runs into the situation that vavuum pump breaks down or when having a power failure, the suck-back phenomenon can appear in separatory funnel, and it is slower to cause liquid to enter separatory funnel speed, and the suction filtration effect is relatively poor.Therefore, need provide a kind of new technical scheme to solve above-mentioned technical problem.
The utility model content
The purpose of this utility model provides that a kind of suction filtration is effective, the chemical experiment of anti-suck suction filtration device.
The technical scheme that its technical problem that solves the utility model adopts is:
Chemical experiment suction filtration device, comprise filter and air extractor, described filter comprises crucible and separatory funnel, described crucible opening part seals by the elastic caoutchouc circle, described separatory funnel bottom is equipped with speed-regulating switch, be connected by flexible pipe between described filter and the air extractor, described flexible pipe is provided with the anti-suck device, described air extractor comprises water inlet pipe, airtight container and outlet pipe, described water inlet pipe lower end is connected with the outlet pipe upper end by interior pipe, pipe is located in the airtight container in described, and described outlet pipe is arranged with receiver.
Described anti-suck device is a utricule, is provided with sealing ring near the separatory funnel side in the described utricule, is provided with ball in the described utricule.
Described receiver is a beaker.
The beneficial effects of the utility model are: the flexible pipe between filter and the air extractor is provided with the anti-suck device, can prevent in the suction filtration process that speed-regulating switch can be controlled flow stream velocity because of the vavuum pump suck-back that is out of order, and suction filtration is effective.
